It's a unique property in the city. Not a public housing project, but controlled by the city government, which collects rent from the folks living there.
Resident tenents say their units are supposed to have been transferred to tenant ownership, and according to a 2015 SF Weekly story, they are correct:
"The Midtown Park Apartments, a block of unremarkable buildings in the Fillmore District, were built in 1964 atop land cleared during San Francisco's 'Urban Renewal' projects. Transformations of Edwardian and Victorian neighborhoods into concrete blocks were hailed by anti-'blight' groups. Critics, like author James Baldwin, had another name for the improvements: 'Negro removal.'
"At Midtown's ribbon-cutting ceremony, then-Mayor Jack Shelley waxed optimistic, calling Midtown a "successful experiment" on the way to 'our ultimate goal...a home for all who wish to live in San Francisco.'
"The 139-unit, three-story project was unique in that it was financed by the city. Once the city's mortgage was paid off, the residents — members of a nonprofit cooperative — would own their places outright. 'Own your own,' as the original sales brochure hyped."
